I try to talk about policy issues intelligently, I try very hard to avoid thought bubbles. I make sure my speeches are well researched and footnoted. I make sure I am not talking through my hat.

I am an ambitious person, but I am not ambitious in the sense that I want jobs only for the sake of them... I am here to do things I think are worthwhile. I am always careful that the political positions I take are consistent with good policy. I would not want to be prime minister of Australia at any price.

Well, human security is a concept that I am very committed to enshrining in American foreign policy.

I am not good at small talk. I will hide in a cupboard to avoid chitty-chat.

I don't mind talking about 'what might have been,' but I am not one to doubt or regret most of my decisions.

I almost always have a strong passion about the things I do. I wouldn't say aggressive, but I am always trying very hard to make sure that things will succeed.
